What do you think this was about?

"I'm getting uncomfortable," Benicio del Toro said after fielding a question about his new movie's portrayal of the Bolivian and Cuban revolutions. "I'm done. I'm done, I hope you write whatever you want. I don't give a damn."

With that, the Oscar-winning actor walked away, abruptly terminating an interview conducted late last week to discuss director Steven Soderbergh's "Che."

What del Toro was experiencing was cognitive dissonance and the implications of his scamper are very interesting for the left-wing worldview that so many people accept uncritically because they've never seen it challenged. For those of you unfamiliar with the term:

Cognitive dissonance is an uncomfortable feeling caused by holding two contradictory ideas simultaneously. The "ideas" or "cognitions" in question may include attitudes and beliefs, and also the awareness of one's behavior.

In any kind of monoculture, the worldview is simply accepted whole cloth and as long as the individual can stay in the monoculture, they can live their whole lives secure in their certain knowledge.

Its when they stray out of the warm embrace of the monoculture that things get hairy.

I think you might be able to extrapolate from this observation that its primarily lefties that experience this. Conservatives have endured relentless challenge to their views their entire lives, so are understandably far more comfortable discussing and defending them than your average liberal.

Now you know why Rush Limbaugh is such a scary guy.
